Is a rebuilt motor just as good and/or reliable as a brand new motor?

Question:
I know that after a while some people get the motor of their cars rebuilt. So, I was wondering if a rebuilt motor is just as reliable as a brand new motor. And, what exactly do they do when they rebuild a motor? Not that I am going to rebuild a motor any time soon, I just was curious.

How often should you change the oil in your car?

a rebuilt motor can be as good, it depends on the machining equipment that the rebuild shop has. the closer the measurement and the flatter the deck the better. and what they do is dissasemble your engine, remove the pistons and crank, wash em off. machine the cylinder head and block. they will check to see if your cylinder walls are scored up. if so they will make the cylinders a little bigger and put new pistons in to match the new size. if the walls are ok then they willl probably just clean them up with a wierd looking brush and perhaps use your old pistons. its all a matter of what you want to spend. theyll probably give you a rebuilt head and use yours as a core, slap it all together for you and paint ugly spots with metal colored paint. thats it in a nutshell.

My 2000 ford ranger starts vibrating at 60 miles per hour or higher, but it quits when I let off the pedal?

It all depends on the rebuilder. Late model engines are built to very close, exacting tolerances. If the rebuilder has the equipment and expertise to maintain those tolerances, it should last as long as the original. All machined surfaces must be checked, and re-machined if any variance is found. All moving parts are replaced, except crankshaft, connecting rods, camshaft and valves, which are re-machined. Sometimes they need to be replaced if they are worn beyond repair.

What is a cold air intake? is this an intake? jwt pop charger? http://www.importpartspro.com/jwtpopcharger.htm

a re built motor is sometimes better than stock just because a good mechanic will go through everything like new crank,new rods,new pistons and new camshaft. line bore all the holes in the block and micro polish every journal.
so the engine is tighter than a new engine because the car makers put out 100s of engines a day and only check 1 of 10 maybe.
if you rebuild your engine don't get cheap parts and don't skimp out. get every part for the engine down to the last bolt. and recheck every thing as you go. that's is why if i want a rebuilt engine i do it myself not some shop were you cant see what they are doing to it. For the big stuff i have a machine shop do.
